PVC Control Joint

Extruded from a specially formulated PVC compound with 85 durometer hardness conforming to ASTM D 2287 Type 654, ASTM D 240. It is designed for use in solid or cavity masonry wall construction at pilasters, columns, inter-sections or other joints. In long walls, control joints at 30-foot intervals are recommended to provide resilient resistance to cracking under stress of expansion and contraction.
